Rob,

The link for Chapter 11 - Stress and Strain in Glass results in Error 404-Not Found.

The only sure way to do it is to go with borosilicate decals. These are water-slide on (like a temporary tattoo) that must then be baked on at about 1100 F. Your issue will be that there's a setup charge for most of these, and there's usually a lead time.

Given your needs, I think the solution is to order page size sheets of numbers, letters, words, phrases etc. that you can cut out an apply to create the markings you need without running up a huge bill for individual setup or having to wait for custom printing. You will, of course, need an oven/furnace capable of getting up to the required temperature and allowing the glass to cool back down slowly.

If you do a web search on "borosilicate decals" you=E2=80™ll find a bunch of suppliers. If you are looking for recommendations, almost any scientific glassblower (and many art glassblowers) can give you one.

One other purchase you may wish to make is a polariscope. There's a writeup on glass stress and strain as well as polariscopes at our Scientific Glassblowing Learning Center page: http://www.ilpi..com/glassblowing/glassstress.html

Best wishes,

Rob Toreki

Our synthesis research lab has been discussing how to set up an inventory for all laboratory glassware beyond the quantity of each item. I was curious if there was a way to track each piece.

For example:

We have 4 100-mL single neck round bottoms.

Over the past 5 years we have bought 12 of these round bottoms. 8 have been cracked/broken/borrowed/etc.

Is there a way to keep track of each of the 12, so that we know which dates the 4 we currently have were purchased?

Ideally the marking/labeling/serial number/etc. would:

- Not compromise the integrity of the glassware

- Be able to withstand the high temperatures of reactions (up to 290C)

- Be able to withstand a dishwasher cycle for cleaning

- Be resistant to Acetone/MeOH/Water

Goals of this inventory:

- Track age of glassware.

- Be able to list specific glassware used in reactions for continuity and sources of variables.

- Restrict certain pieces to fragrance synthesis only.
